During a single knee procedure, such as a TKA, the knee transitions repeatedly through multiple positions for exposure, balancing, trialing, and assessment. 

Each transition introduces the potential for instability, ergonomic disruption, and interruption to surgical flow.

The RAMP stabilizes the knee at key flexion angles while allowing unrestricted movement between them.

The RAMP is used in a wide range of knee surgeries, including TKA, revision TKA and various sports medicine applications

Product overview

The RAMP provides six stabilized knee flexion positions at approximately 55°, 90°, 115°, 140°, and 150°.*

Between these positions, the leg remains completely unconstrained. This enables unrestricted soft tissue assessment and quick, dynamic registration for computer navigation without removing or reconfiguring the device.

The RAMP is installed at the foot end of any standard OR table and sits below the sterile drape.

*Exact angles depend on setup technique and patient anatomy.

Built for Efficiency

The RAMP offers more flexion compared to a simple sandbag or bump, without the hassle of complex sterile systems.

  • Stable, hands-free support in all six knee positions
  • Unconstrained manipulation between positions
  • Reduced need for manual leg holding or adjustment
  • Flat, firm, proximal-facing pad surface provides stable positioning for the sole of the foot
  • Soft, rounded distal side of the pad protects the Achilles tendon

The raised-foot design also facilitates full knee extension, particularly in patients with larger thighs.

Setup, compatibility & practical fit​

The RAMP is designed for fast setup and efficient turnover.

  • Secures to any standard OR table using two Velcro straps
  • Installs quickly at the foot end of the table
  • Sits entirely below the sterile drape
  • No autoclaving required
  • No sterile consumables
  • No moving parts

The device is lightweight, easy to store, and requires minimal maintenance.

Product Specifications
"We have been using The RAMP for over a year in all our robot-assisted knee replacements with a two-person setup. It has proven itself exceptionally well and enables effortless and stable fixation of the knee in all necessary positions."
Johannes Erhardt, MDHOCH Health Ostschweiz, Grabs SG, Switzerland 
"The RAMP performs as advertised, it holds the leg stable in different positions during knee surgery. It allows us to focus on the surgery rather than making sure the leg doesn’t move out of the optimal position, especially with high BMI patients."
Hasham M Alvi, MDBarrington Orthopedic Specialists, Schaumburg, IL, USA

The RAMP is used in routine and complex knee procedures, and is available for evaluation through a free trial.
